  • Patent number: 8967501
    Abstract: The invention relates to a valve arrangement (2) for metering a fluid medium into an exhaust line (22), comprising a valve seat (10) which acts together with a closing body (12) and in which a valve passage (14) is implemented, and a perforated disc (6) that is disposed downstream of the valve seat, closes off the valve passage, and has at least one axial hole (8) in the area of the valve passage through which the fluid medium can be injected into the exhaust line (22). The valve arrangement further comprises a connecting flange (16) for connecting the valve arrangement (2) to the exhaust line (22) in a fluid-tight manner, wherein the perforated disc (6) extends from the valve passage to the connecting flange and is implemented such that said perforated disc seals the connecting flange against the exhaust line in a fluid-tight manner in the installed state.
